To all 1071 0727 it may concern:

Be it known that I, FRIEDRICH KLEIN- VOGEL, a citizen of the UnitedStates, residing at Newport, Kentucky, have invented certain new anduseful Improvements in Driving Mechanism with Alternately-Acting Levers,of which the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The present invention relates to mechanisms driven by foot-power bymeans of two levers arranged on both sides of a seat and acted uponalternately, and the motion is employed for the propulsion of vehiclesfor pumping or for any other purpose.

An ordinary lever fulcrumed at one end and having a pedal for foot-powerat the other end requires a large stroke in acting on a crank of anypart of machinery. It is the object of this invention to decrease thestroke of the lever or to admit of the use of a largercrank-arm, so thatthe power may be transferred more easily. To this end a treadlelever isconnected with a special lever system, as hereinafter described, andillustrated in the accompanying drawings, in which Figure 1 is a sideelevation of a carriage to which the new lever system is applied. Fig. 2shows the lever system separately in the highest position, and Fig. 3shows the same in the lowest position.

A frame a of any suitable shape and material is provided in the ordinaryway with the front axle 6, having wedged thereto at one end adriving-wheel and at the other end a loose wheel 0 c. In the rearsmaller wheels (Z (Z are provided, being connected in any suitablemanner with a steering device e in front of a seat f, resilientlysupported on the frame.

Motion is transferred to the aXle b by means of sprocket-wheels g h anda chain '5. (Indicated in Fig. 1 in dotted lines.) A flywheel k may bearranged on the frame and connected with the mechanism to even out themotion. The shaft of the sprocketwheel g has a crank l on each end, thecrankpins being provided with rollers 'm, and on these rollers themechanism to be now described is acting, thereby producing motion of thevehicle. To the rear of the frame the treadle-levers are pivoted at m,having at the forward end a treadle in the vicinity of the seat f.

Springs 0 can be employed to draw the levers into an elevated position.

Arms p are pivotally connected to the frame somewhat in front and belowthe pivots n, and at their upper ends triangles g are hinged, theforward corners of which are pivotally connected with the treadle-leversm by means of links r. s is a lever hinged to the front part of theframe and having at its rear ends two pivots s and the upper one, 8,being connected by a link if to the forward corner of the triangle g andthe lower one, 8 being connected by a link a to the lower corner of thetriangle g.

The levers 3 act directly on the rollers m of the cranks. When atreadle-lever is in the highest position and the corresponding lever siselevated, the pressure of the foot is transferred upon the same by meansof the triangle 9 and the link a pulling the lever 8 down, While thelink 1. at the beginning of the motion cannot act on the lever 8. Whenapproaching to the lower position, the triangle g, receiving the pull ofthe treadle-lever n, gradually ceases its pull on the lever s by meansof link a and presses the same down by means of the link 15, as can beeasily seen from Figs. 2 and 3.

The upper pivot of the link 7 is arranged near the upper pivot of thelink If, and the throw of the lever s with the transfer on thecrank-pins may be varied at will by varying more or less the distance ofthe pivot of link 1 from the front corner of the triangle g.

Having thus described my invention, what I claim is 1. The combinationwith a frame, of a shaft carried by the frame and having at its endscrank-arms provided with rollers, levers pivoted to the frame andengaging the rollers of the crank-arms; treadle-levers, and connectionsinterposed between the treadle-levers and the crankengaging levers, eachconnection comprising an element pivoted to the frame and linksconnecting the pivoted element to a treadle-lever and to acrank-engaging lever.

2. The combination with a frame; of a driven shaft mounted thereon; adrivingshaft having at each end a crank-arm provided with a roller; afly-wheel rotatably supported upon the frame; sprocket-wheels andcoacting chains adapted to transmit motion from the driving-shaft to thedriven shaft and to the fly-wheel; crank-operating IIO levers pivoted tothe frame and engaging by rolling contact the rollers of the crank-armstreadle-levers pivoted to the frame; triangle connections each pivotedat a vertex to a bar hinged to the frame, and connected by links at theother vertexes to a crank-actuating lever, and links connecting thetreadle-levers to the triangular connections.

3. The combination With a support, of an actuated lever pivoted thereto,an operatinglever pivoted to the support, and a triangular connectionpivoted to the support and connected .to the actuated lever and to theoperating-lever.

4. The combination with a support, of an actuated lever pivoted thereto,an operatinglever pivoted to the support, a triangular connectionpivoted at one vertex to an arm hinged to the support, and connected bylinks, at the other vertexes, to the actuated lever; and a linkconnecting the operatinglever With the triangular connection.

In testimony whereof I aflix my signature.

FRIEDRICH KLEINVOGEL.
